In theory, you can get a sharp image through turbulent air indeed by taking dozens or better hundreds of captures and then superimposing them in a clever way. However there is no post-processing software actually supporting this. You could write your own program (google for "ImageJ", for example) that runs a statistical analysis on each pixel across all captures and then paints that pixel in the resulting image according to some sophisticated algorithm. This should be able to get rid of, or at least reduce, the atmospheric blur. In practice, this would be very tedious to do, and you still cannot take satisfying results for granted. The degree of success would depend on many factors, among them the frequency of the turbulences, the magnification (focal length, distance), and how accurately the multiple captures are aligned with each other.
Generally, it's best to do telephoto landscape shots in the early morning, within an hour or so after sunrise, or when the sun breaks through the clouds right after a rain shower.
